One of the features we could kind of use and miss in the Material UI, is a pull down scroll rect to refresh / update content that is in the scroll view.

I already saw a feature request for cards, so what we would love to have is a list of cards that can be updated through the scroll rect by pulling it down to refresh the cards with up to date information.

This would also be a nice example scene where you have a nav drawer, a app bar and a list of cards :)
